Aguilera was onboard with the unconventional procedure without hesitation.

A similar operation occurred earlier this year when Anthony Kulkamp Dias also underwent surgery to remove a tumor from his brain and played the guitar to keep himself awake and entertained as surgeons operated. His tune of choice was an acoustic rendition of "Yesterday" by the Beatles.
